Much appreciate if anyone online now can help me with this question.

No need nice diagram, I am having a brainblock and can't work out how to cut the units ! Thanks in advance :

Kamala had 5026g of flour in a bag. She bought another packet of flour of mass 4157g. She transferred some flour from the packet to the bag. The mass of the flour in the bag became twice the mass of the flour left in the packet. How much flour was in the packet in the end ?

Total mass of flour = 5026 + 4157 = 9183g

Bag : Packet is 2:1
So packet has 1/3 of the total mass = 1/3 x 9183 = 3061g

I used algebra.
Flour left in the packet is 3061g.

5026+ X = 2(4157 - X)
3x = 3288
x = 1096
what's left in the packet is 4157 - 1096 = 3061g

Can somehow use algebra and turn into model or not :lol: ?
